I did a test on windows, and it appears we need to skip clipping if the ORIGINAL width and height are <= 0.
Do you mean something like '&& (rect->Width > 0.5) && (rect->Height > 0.5)' added to 'if (!(format_flags & StringFormatFlagsNoClip) && ...' condition ?
This indeed seems to work, though looks potentially fishy.
